Definition of SR, PD, PDI, NRI, NTI, MDT, MDT.youngest, and MDT.oldest are as in Fig. 3. For SR, NRI, PD, MDT and MDT.oldest, the landform effects are coded in reference to Danxia (the intercept). For PDI, NTI, and MDT.youngest, both landform and tectonic effects were coded in reference to the Danxia + craton (the intercept). Compared with Danxia + craton as a baseline, karst, karst-granitic, and granitic mountains located in the orogenic belt have lower NTIs and higher PDIs. Legend colors indicate different explanatory variables, including landform (karst, karst-granitic, granitic, Danxia, desert), tectonic type (Orogen, mountains located in the orogenic belt), geographic (Longitude; Latitude; Elevdiff, difference between the highest and lowest elevation), and climate (Isoth, isothermality; TAR, temperature annual range; TWQ, mean temperature of the warmest quarter; TCQ, mean temperature of the coldest quarter; PREC, annual precipitation) (Supplementary Table 2). The length of each bar represents the explanatory power of the variables. Source data are provided as a Source Data file.
